O'Reilly Auto Parts replaces Xfinity as NASCAR title sponsor

O'Reilly Auto Parts will assume the title sponsorship of the NASCAR Xfinity Series starting January 1, 2026. The auto parts chain, with over 6,400 locations across 48 states, Puerto Rico, Mexico, and Canada, will rename the series the NASCAR O'Reilly Auto Parts Series through a multi-year agreement with NASCAR and The CW Network.

The partnership makes O'Reilly the fourth title sponsor in the series' 43-year history. The Springfield, Missouri-based company, founded in 1957, will take over from Xfinity after its 11-season sponsorship run concludes in December 2025.

Brent Kirby, President of O'Reilly Auto Parts, linked the company's corporate values to NASCAR's philosophy. "Our company is rooted in the same values that define NASCAR: teamwork, enthusiasm, and dedication," stated Kirby. "You'll see them in action when our customers walk through our doors. We know they need fast service, and Team O'Reilly will get them the parts they need quickly, with excellent customer service."

Xfinity Concludes Sponsorship After 11 Seasons Since 2015

The series has experienced multiple title sponsorship changes since its establishment as a national competition. Anheuser-Busch held the sponsorship from 1984 to 2007 under the names Busch Grand National Series, Busch Series, and NASCAR Busch Series. Nationwide Insurance took over the sponsorship from 2008 to 2014, followed by Xfinity since 2015.

Brad Schwartz, President of The CW Network, attributed the television success to consistent viewership. "NASCAR's success on The CW has proven that millions of fans will consistently tune in to these adrenaline-filled races every week," said Schwartz. "This new alliance with O'Reilly Auto Parts gives us the opportunity to expand that reach even further by leveraging our strong mutual presence in local communities and continue growing our passionate audience in the years to come."

Hugo Sanchez, Vice President of Advertising and Marketing for O'Reilly Auto Parts, confirmed the long-term strategy. "Partnering with NASCAR and The CW at this level allows us to deepen our connection with one of the most loyal fan bases in all of sports," Sanchez stated. "This agreement builds on our long-term involvement in NASCAR and our dedication to the fans who love cars as much as we do."

The NASCAR O'Reilly Auto Parts Series will officially kick off on February 14, 2026 with the season's first race, maintaining its role as a development platform for future stars of the NASCAR Cup Series.
